Description

连接器
技术领域
本发明涉及连接设备与电缆的连接器,特别是涉及汽车等产生振动的环境下所使用的连接器。
背景技术
汽车等具有的电力转换装置等设备与电缆的连接使用连接器。以往的连接器结构由图4及图5所示。如图4及图5所示,连接器具有安装在设备上的外连接器和安装在电缆16上的内连接器。外连接器具有外壳1、内壳2及阳端子3,内连接器具有外壳4、内壳5及阴端子6。内连接器中,外壳4由铝构成,具有插通电缆16的开口部。电缆16上设置有组合屏蔽,为了实现组合屏蔽与外壳间的导通,在组合屏蔽上夹紧有外部金属环30。
如图6所示,外部金属环30具有:夹紧电缆16的组合屏蔽的电缆夹紧部31;与外壳4接触的弹簧部32。
如图4所示,内连接器还具有:容易进行卡合的手柄10;固定卡合后的手柄的CPA11;进行外/内连接器间防水的垫圈12;进行电缆/外壳间防水的电线密封13;用于固定垫圈的尾板14。
[专利文献1]特开2008-102366号公报
在汽车等产生振动的地方安装连接器时,安装在连接器上的电缆上会产生摇晃。这时,摇晃会传达到与电缆连接的内连接器内部的阴端子6上,阳端子3与阴端子6的接触部上会产生摩擦。由此,由表面镀层的磨损等影响,会导致阳端子3与阴端子6的接触电阻增大。
即,以往的连接器中,如图7所示,电缆16与连接器的壳(阴外壳4)通过设置在外部金属环30的弹簧部32的圆周方向上的多个突起部33接触。这时,弹簧部32与外壳4的接点在电缆16的圆周方向上有多个点,但在长度方向上只有1处接触,所以如图7虚线所示,以弹簧部32与外壳4的接触部为基点摇动,电缆16的摇晃传达到阴端子6上,其结果,由于此摇晃,阳端子3和阴端子6的接触电阻增大。
发明内容
本发明的目的在于解决上述课题,提供在汽车等的振动环境下也能降低外/阴端子间的表面磨损的连接器。
本发明所涉及的连接器具有:金属环,其与在导体外周覆盖绝缘体及组合屏蔽而构成的电缆连接;壳,其容纳该金属环并具有与上述组合屏蔽导通的屏蔽部;上述金属环具有:电缆夹紧部,其夹紧上述电缆且与上述组合屏蔽导通;弹簧部,其将该电缆夹紧部及上述电缆固定在上述壳内并与上述屏蔽部接触,其特征在于,上述弹簧部设置在上述电缆夹紧部的两端侧。
根据本发明,在汽车等振动环境下也能降低外/阴端子间的表面磨损。

具体实施方式
下面参照附图来说明本发明的实施方式。
图1是表示本实施方式的连接器的剖视图。本连接器的外观与图4所说明的以往连接器大致相同,相同的结构部分由与图4相同的符号表示。
如图1所示,本实施方式的连接器具有:安装并连接在电气设备上的设备侧连接器(第1连接器)21;安装并连接电缆的电缆侧连接器(第2连接器)22。
设备侧连接器21中,由绝缘性树脂构成的阳内壳2固定在薄片端子结构的阳端子3外周,阳内壳2固定在由铝形成的阳外壳1上。
电缆侧连接器22中,由绝缘性树脂构成的阴内壳5固定在插座接点结构的阴端子6外周,阴内壳5固定在由铝形成的阴外壳4上。阴端子6与阳端子3通过设置在阴端子6内的弹簧结构,以一定的接触力互相接触。
电缆16是以导体为中心、依次覆盖绝缘树脂、组合屏蔽、铠装的屏蔽电缆。导体被阴端子6的筒部61夹紧,与阴端子6导通,组合屏蔽通过外部金属环7与阴外壳4导通。电缆侧连接器22中,在阴外壳4内侧设置有防水用垫圈12,设备侧连接器21与电缆侧连接器22卡合时,由阳外壳1和阴外壳4压住垫圈12,由此保持防水。电缆16与阴外壳4之间设置有电线密封13和压住电线密封13的尾板14,确保阴外壳4内的防水。
并且,电缆侧连接器22上还设置有:手柄10,其机械地辅助阳端子3连接到阴端子6的动作;CPA(Connector Position Assurance),其固定该连接动作后的手柄10(参照图4)。
图2是表示构成本连接器的外部金属环7的立体图。图3是其剖视图。如图2及图3所示,外部金属环7具有夹紧电缆16的电缆夹紧部(以下称为“夹紧部”)8和设置在夹紧部8两侧的弹簧部9。
夹紧部8由导电性材料形成,其内周面为圆筒状的筒体。夹紧部8设置在组合屏蔽外侧,该组合屏蔽在电缆16的铠装外周上设置的内部金属环17上折回,外周面的剖面为多边形(图中为正六边形),与组合屏蔽导通。
弹簧部9设置在电缆16的外周,朝阴外壳4的圆筒内面有弹性且为与阴外壳4的圆筒形大体相同的圆筒状板簧。弹簧部9在电缆长度方向上形成切口,分成3个以上。并且,分割后的各板簧上分别形成突起部15。通过该突起部15,弹簧部9插入阴外壳4内时,通常与阴外壳4的内面(屏蔽部件)接触。
这样,电缆16的组合屏蔽通过夹紧部8、弹簧部9与阴外壳4的屏蔽部件导通。
根据本连接器,通过在夹紧部8两侧设置弹簧部9来构成外部金属环7,电缆16在电缆长度方向上由2处弹簧部9与阴外壳4连接,并被其支持,所以连接器上有振动时,能够抑制电缆16的摇晃传达到阴端子6上,能够提高连接器的耐振性能。其结果,在汽车等振动环境下也能降低阳/阴端子间的表面磨损。
并且,本发明的外部金属环7由1个夹紧部一起夹紧其两侧设置的弹簧部9,所以与分别夹紧每个弹簧部相比,制造效率非常好。
本发明并不限定于上述实施方式,还可以有各种变形。
